Do-it-yourself cleaning of the gas boiler AOGV-11.6-3

Model overview

Any AOGV is a single-circuit floor-standing device designed for heating a room.
There is no second circuit in them. If you need hot water supply, you need to connect an indirect heating boiler. Based on AOGV, AKGV is produced - they have a built-in heat exchanger for hot water supply. The burner is designed for natural gas. To convert the device to liquefied gas, you will need to change it and need a special nozzle. The manufacturer produces heaters with power from 11 to 29 kW. You can choose a modification for heating an area from 45 to 250 m². The estimated cost of ZhMZ boilers is 18-23,000 rubles.

The abbreviation stands for “Gas Water Heating Apparatus”. The Zhukovsky plant is not their only producer. They are released:

JSC "Borinskoe" (Moscow region). It produces devices in an expanded power range; there are models for 5, 6, 7, 9 and 11 kW. Next: from 11 to 23 kW.
CJSC "Rostovgazoapparat" Produces options 11.6-35 kW.
There are also imported versions - Beretta (Italy).

Zhukovsky MZ does not produce parapet boilers, but they can be found from other domestic manufacturers, for example, a device from the ROSS company. Parapet models have a closed combustion chamber, so they can be installed in an apartment. They do not require a separate room.

Example of a parapet device: ROSS AOGV-13P. This is a 2-circuit option. Heats up to 130 m². 13 kW. Efficiency - 90%.

Types of devices

All single-circuit and double-circuit AGVs produced by Zhukovsky have three main varieties, which allow customers to choose a heating column depending on their available budget:

“Economy” modification - has a set of equipment necessary only for safe operation: domestic automation, temperature sensor, heat exchanger.
The “Standard” variation is also capable of modulating the burner flame, is controlled by a foreign control system, and can turn off when overheated, preventing damage.
The Comfort boiler complex is distinguished by the presence of a remote control unit, technology for maintaining the set temperature, and a room thermostat.

Preparing the cleaning solution

The detergent (powder or liquid concentrate) is poured into the expansion tank gradually, in accordance with the recommendations for preparing the solution.

If we talk about Kratol K, we recommend using an 8-10% solution at a temperature of about 60°C. Those. for 9 liters of water you pour 1 kg of Kratol K

Attention! The reaction releases carbon dioxide, which squeezes water out of the boiler. That is why we said that the intermediate tank should be larger than the volume of the boiler being washed

Therefore, pour in carefully, let the powder gradually stir, and you will control the process of gas formation.

You can judge the effectiveness of the reaction by the gas that will be released into the intermediate tank, foam will form, and the washing solution will darken and become cloudy.

Keep an eye on these indicators. In principle, you can increase the temperature to 60°C (but no more, otherwise acid hydrolysis will begin and the effectiveness of chemical washing will decrease) and increase the concentration of the solution to 10%. Don't worry, nothing will happen to the boiler, especially if you use our detergent. Monitor external parameters. Dilute the acid gradually. Heat gently. In our practice, it also happened that we overheated the boiler, and then boiling acid gushed out in all directions. Not particularly dangerous, but unpleasant.

By the way, about gases. In order to squeeze out the gases that accumulate in the upper part of the boiler and are formed during the reaction of the flushing liquid with scale, we practice periodic stopping of the pump. In this case, a small water hammer is created (for the coil being washed it is not scary, since in such pumps the maximum pressure does not exceed 2 atm) and the air is gradually pushed into the expansion tank. Those. During flushing, we stand nearby, watch the liquid level in the expansion tank and periodically turn the pump on and off.

Types of pollution

For the operation of a solid fuel boiler, raw materials are required, due to which the combustion process will be carried out. Firewood, coal, peat and pellets act in this capacity. Each type of raw material has its own advantages and disadvantages. A common property is that during operation of the boiler, combustion products are released, which gradually accumulate on the internal parts of the chamber.

There are three main substances that pollute a boiler. The presence of each of them is due to certain factors:

soot. Appears when the temperature during combustion of raw materials is not high enough. This is also affected by a lack of oxygen;
resin. As a rule, its occurrence is due to various problems with the fuel: it may be too wet or of poor quality. Or you simply loaded too much raw material into the combustion chamber. A negatively influencing factor is also insufficiently high temperature;
tar. The appearance of this substance indicates possible problems with the equipment itself. Either errors have crept into the design of the boiler, or the chimney was made too short, or the air flow is pumped into the chamber too weakly - the last factor is relevant for pyrolysis equipment.

Someone might think that a dirty boiler is not so bad, because all the deposits are hidden inside. In fact, the consequences can be quite negative. The performance of a solid fuel boiler depends on its cleanliness. With a high level of pollution, it will greatly decrease, as a result of which the house will become much colder, since the equipment simply will not be able to cope with heating the required volume of coolant.

In addition, such an attitude towards the boiler will lead to increased costs. First, fuel consumption will increase more and more as deposits accumulate inside the combustion chamber. Secondly, the boiler itself will quickly fail, and you will have to spend money either on repairing it or purchasing new equipment.

All these problems can be avoided quite simply:

use only high quality fuel; Initially, when choosing a boiler, pay attention to the compliance of its design with technical parameters; Perform preventative cleaning regularly. All this will significantly extend the service life of the equipment.

All this will significantly extend the service life of the equipment.

Other models

In practice, cleaning burners follows the same principles. The differences lie in their removal and reassembly.

The following examples are provided:

For example, the Helios AOGV 4 parapet apparatus is equipped with Eurosvit 360 automation and burners of the European brands Bray and Polidoro.

The burner set is removed following the example of the Zhitomir process. A pump is used to clean the nozzle, and hard brushes are used to clean the surfaces.

The Conord line stands out in particular.

The automation variations here are:

The most popular is the second variation:

It includes a sectional burner, Polidoro tubes, igniter, thermocouple, gas valve, temperature indicator and wires.

A similar system is available in the Lemax Premium 12.5 model.

Only the burner here is micro-flare. The mechanism is very easily removed by removing the top cover and lightly unscrewing the fixing bolts.

Its analogues are also found in the Siberia models.

Ecological burners "Vorgas" are used here.

Does not lag behind in this regard. Here its models Novella Maxima 108 N RAI and Mynute Boiler stand out.

Honeywell automation looks like this:

It has a similar operating principle to the Eurosvit system. The differences lie in the materials of some components.

It is often found in wall-mounted modifications, for example in Baksi Fortech 24

It also has an ecological burner that leaves no combustion products.

An equally popular device is the Ariston ALTEAS X 24 FF NG.

Many Daewoo models operate with similar automation. For example – DGB 200 MSC.

Whatever model or brand you have, strictly follow the suggested instructions for removing and financial assistance grants for reinstalling the burner unit. Clean it thoroughly with the right products 1-2 times a year. Maintain other mechanisms as well. And then your boiler will work properly for a long period.

An indispensable attribute of any heating system is a boiler, which acts as a heat generator for heating the home.

The modern heating equipment market is saturated with a very wide range of boiler units of various types. But a special place in this range is occupied by gas boilers, which are becoming more and more popular every day.

This trend is due to the fact that units of this type are very effective and economical devices for heating a country house or even an apartment. In order for a gas boiler to function smoothly and stably, it is necessary to properly care for it.

One type of such maintenance is cleaning the gas boiler from soot and other contaminants. Let's talk in more detail about why to clean a gas unit, as well as in what ways this can be done.

AKGV series

Floor-standing boilers with a double-circuit heating system are also presented here. Boilers of this series require high-quality ventilation, which will remove combustion products, and a separate room. True, as reviews of models in this series show, you can also buy a gas boiler for installation in the kitchen.

The burner power in these units varies from 11.5 to 29 kW. The most popular model has a power of 17 kW and heats a room of 150 square meters. meters
The boiler is equipped with a bithermic heat exchanger - a coil is installed inside the tank, which is responsible for heating the water to the desired temperature
The burner of the device has anti-corrosion properties
Heating equipment is equipped with a thermostat, temperature control system and control of gas supply and draft in the system

Also, the AKGV series is distinguished by the fact that the outer walls do not heat up during operation, and during sudden gusts of wind the draft will not disappear thanks to a special stabilizing element.

You can buy a Borinsky heating boiler of the AKGV series for $250, and you can buy Borinsky gas heating boilers with a higher power of 23 kW for $360. What do reviews say about the powerful heating boiler model AKGV 23?

Anastasia, 32 years old:

I’m glad that this model is non-volatile; constant power outages are always a problem for parents. It also heats the water quite well, but I can’t say that the pressure is enough for all needs – it’s enough to wash the dishes.”

3. AOGV series - here are gas single-circuit boilers designed for space heating. Devices in this series are floor-standing units that run on natural gas.

AOGV models are manufactured in a cylindrical body and are represented by several “subseries” - an economy version with a Russian-made control unit, a universal device with a control unit from Italian brands, and a comfortable unit, where the automation is presented by a German manufacturer.

Borinsky AOGV floor-standing gas boilers have thermal power from 11.5 to 29 kW.
Designed for heating rooms from 40 (at minimum power) to 250 sq. meters (maximum boiler power).
Gas boilers are equipped with an automatic system for stopping the gas supply in the absence of draft and ignition on the burner.
Equipped with a thermostat with a temperature range up to +95 degrees.

You can buy a Borinsky boiler of the AOGV series for 220 USD. – such a model will have minimal power; a unit for a large house with maximum power will cost $450-490. Let's look at the reviews of the mid-price model with a power of 23 kW.

Alexander, 37 years old:

In general, I bought a model with Italian automatic equipment for my 150 square meters. I want to say that the efficiency is really about 90%, and the gas consumption is small - about 1.7 kg/hour (cylinder). I’m happy with the device and I couldn’t be happier for six months now.”

4. The KOV series are single-circuit floor-standing boilers, which are distinguished by high power and are designed for heating large rooms.

Borinsky KOV boilers have a power from 30 to 63 kW;
Equipped with automatic equipment from an Italian manufacturer;
Designed for heating areas from 250 to 750 square meters. meters;
Gas boilers are equipped with a protection system in the absence of draft, gas supply interruption and absence of an igniter on the burner.

You can buy a Borino boiler with a power of 30 kW for 600-660 USD, a boiler with a power of 50 kW for a room of 500 square meters will cost 820-860 dollars.

Choosing a Borino boiler

Before you buy a Borino gas boiler, decide what you need it for - will it only perform a heating function, or do you need a double-circuit model.

Look at the power - if your house is insulated, you can choose a boiler commensurate with the area of the house. If your house is “cold”, take a model with “power reserve”
Look at the automation - all floor-standing boilers are equipped with a protection system, but the automation itself can be of domestic or foreign production
Look at the combustion chamber and air outlet - the chamber can be closed or open, run on natural gas or from a cylinder. Some models may require replacement of injectors to operate on liquefied gas.

Work carried out and its frequency

Before the start of the heating season and after it, you need to perform a number of procedures, including cleaning:

igniter;
burners with nozzles;
gas filter;
heat exchanger;
combustion chambers;
chimney.

If some negative aspects arise, there is no need to postpone this matter and you need to clean the device immediately:

If the boiler is operating in standard mode, but the room temperature has become lower.
The unit began to consume more gas and electricity.
The smell of carbon monoxide began to be heard in the room.

How to calculate the gas consumption of a boiler?

Often such situations arise as a result of a clogged boiler. In order to correctly identify the area of contamination, you need to have special knowledge regarding the design of a gas boiler.

Let's take a closer look at how to clean each component of a gas boiler.

Prerequisites for the cleansing procedure

It must be promptly implemented when the boiler:

It begins to weakly heat the room.
Consumes a lot of electricity and gas.
It works in such a way that a burning smell appears in the room.

As a rule, such failures are caused by blockages. And it is necessary to thoroughly clean all the important components of the boiler, and especially the burner.

These elements include: igniter, filters, combustion chamber, heat exchanger and chimney.

Cleansing should be done 1-2 times a year. This will be the key to safe and reliable operation of the equipment.

How to proceed with models of certain brands is shown below.

Features of cleaning boilers of different brands

Depending on the manufacturer of the water heating equipment, cleaning may have a number of nuances that must be taken into account. Let's look at the most common brands.

Baxi

The main feature of Baksi boilers is the presence of a secondary plate heat exchanger. This is worth considering when choosing a cleaning product.

Navien

A South Korean manufacturer that produces water heating products adapted to Russian conditions. When washing it, no problems arise, since the system has increased stability and reliability.

Ariston

Ariston equipment is equipped with additional water purification filters, which is why the water entering the system is cleaner than usual. This allows you to go without cleaning for a long time and use gentle options when choosing chemicals.

Vaillant

The operating temperature recommended by the manufacturer is within 40-50 o. If you follow this, scale will accumulate in the heat exchanger more slowly.

Beretta

A high-quality manufacturer that adapts its products to Russian realities. Does not have any special features during cleaning. It is carried out by analogy with most similar products.

Arderia

Another brand from South Korea, equipped with two heat exchangers. If the product does not operate correctly, it is advisable to clean both parts.

Causes and consequences of clogging

Energy-dependent ones are in turn divided into:

gas processing;
electrical installations;
solid fuel and liquid fuel equipment;
combined models.

Volatile boilers may turn off for a number of reasons:

voltage drops and surges in power lines
lack of electricity
factory settings failure.

Often used in homes: AOGV, Zhukovsky boiler, gas “Ochag”, Lemax, Signal, Conord.

Do-it-yourself furnace: drawing, operation diagram. Read here.

Connection to the city water supply network: documents, prices:

Mechanical ones may work intermittently due to wind flow entering the chimney. In addition, due to insufficient oxygen, the flame may go out

You should pay attention to the hood (cheaper models do not always have it)

If the chimney becomes dirty, modern devices have a warning system that will notify you of problems and the need for cleaning.

What is AOGV: decoding

Mechanical automation.

AOGV (interpretation: gas hot water heating apparatus) is a gas boiler that does not contain a single volatile element. That is, the unit can operate autonomously without electricity. They are usually installed where there is a central gas pipeline, but even in the absence of gas, you can change the burner, which will run on propane-butane. In the heater marking there are always numbers after the abbreviation - this is the maximum power. For example, AOGV 17 means that the maximum thermal power of the unit is 17 kW.

Main elements of the heater:

automation;
thermocouple;
combustion chamber;
heat exchanger;
chimney.

The operation of the AOGV boiler is controlled by mechanical automation. Domestic heaters can be equipped with automatic equipment of their own (in cheaper models), European or American production. This is the heart of the heater; without automation, the boiler cannot operate. The second important element of the heater is a copper thermocouple. It is responsible for activating the solenoid valve, which shuts off the gas supply if the burner wick goes out.

Unlike modern parapet heaters, AOGV gas boilers are equipped with an open combustion chamber. The disadvantage of such chambers is that they take air from the room in which they are located to maintain the fire. The advantage is the ability to exhaust smoke through a regular chimney with natural draft; there is no need for an energy-dependent fan.

The heat exchanger is located at the top of the combustion chamber, directly above the burner. Each circuit has its own heat exchanger; the fluids in them do not intersect. That is, if the heater is intended not only for heating the room, but also for preparing hot water, then there will be two heat exchangers.

The most common automation malfunctions and methods for eliminating them

Before setting up the automation on the boiler, it is necessary to diagnose it. As a rule, serious malfunctions occur that will require specialist intervention. The adjustment can also be entrusted to a gas technician. Or you can do it yourself by reading the instruction manual.

Attention! Before each seasonal operation, it is necessary to check the operation of the safety sensors. Most often, the filter becomes clogged, problems arise with the valves, sensors burn out due to power surges, and a gas leak is detected.

Proper cleaning of the filter should be done by a professional. You can try to replace electronic elements yourself by carefully studying the operating instructions for your boiler

Most often, the filter becomes clogged, problems arise with the valves, sensors burn out due to power surges, and a gas leak is detected. Proper cleaning of the filter should be done by a professional. You can try to replace electronic elements yourself by carefully studying the operating instructions for your boiler.

In order to replace the temperature sensor, you need to turn off the gas boiler and cool the water to a temperature of 40 degrees. Shut off the flow of coolant, remove the control knob by unscrewing the screw. Next, remove the PTV adjustment screw. Remove the sensor bellows with the support washer. Unscrew the union nut of the sensor thermal bulb. Install the thermal bulb of a working sensor into the boiler jacket and screw it tightly. Install the sensor bellows into the pipe socket, install the support washer on the bellows, install the PTB adjustment screw and adjust the temperature.

If problems arise with igniting the igniter, then one of the possible causes is a malfunction of the draft sensor. In this case, it must be dismantled, diagnosed, checked contacts, cleaned, and, if necessary, replaced with a new one.

Also, common reasons why the pilot light does not light may be:

gas valve malfunction;
clogging of the hole in the igniter nozzle (it can be cleaned with wire);
strong air draft;
low gas inlet pressure.

When the gas supply is turned off, it is necessary to check the chimney (it may be clogged), the electromagnet, and the gas pressure at the inlet to the gas boiler.

Attention! To diagnose and repair the gas boiler automation, you must invite a specialist. Inept actions can aggravate the problem and lead to undesirable consequences.

For the automation of AGUK, AGU-T-M, AGU-P systems, the most common problem is the burnout of the bimetallic plate, which is used as a sensitive element

For the automation of AGUK, AGU-T-M, AGU-P systems, the most common problem is the burnout of the bimetallic plate, which is used as a sensitive element.

In Arbat and Orion, you can only replace the thermocouple and draft sensor, as well as the solenoid valve (rarely). The automation unit is practically beyond repair. In Arbat, the system shutdown button often breaks down.

Typical problems for SABC automation are damage to the main valve membranes and drying out of the thermostat stuffing box, resulting in gas leakage. Impulse tubes, bimetallic plates, and ball valves are subject to control.

In conclusion, I would like to emphasize once again that automation is designed to maintain the operation of heating equipment in a safe mode. Therefore, it is simply necessary for owners of gas boilers.

This video shows how to troubleshoot an automatic boiler AOGV, step-by-step assembly process and testing the result.

All modern heating installations using natural gas as an energy source have a high level of safety, which is achieved through the introduction of automation equipment. They monitor and manage the operation of heating units. In this material we will consider automation for gas boilers from the most famous manufacturers, which is most often installed on domestic and imported boilers.

Price range

The cost of the Zhukovsky AOGV 23 boiler depends on the specific model and ranges from 20-24.4 thousand rubles. This price does not include the chimney. When purchasing, you should immediately clarify the equipment of the unit so that you do not have to urgently look for the necessary components.

In addition, additional costs will arise for concluding a warranty agreement.

It is not recommended to neglect this action, since subsequently you can spend a much higher amount on repairs.

NOTE!

Many users rely on their own skills and knowledge, intending to repair the boiler themselves. It must be remembered that unauthorized actions with gas equipment may entail administrative liability.

How to determine the need for cleaning

Gas boiler cleaning

Boiler manufacturers recommend servicing equipment once every 1 to 2 years. But the need for cleaning may arise more often, since it all depends on the operating conditions and the specific model. Most often, the heat exchanger needs unscheduled maintenance.

Expert opinion Vadim Savelievich Grebnev Heating systems installer

When using low-quality water, the heat exchanger can become seriously scaly in just a few months. Boilers with atmospheric burners become covered with soot. Operating all models in dusty rooms leads to clogging of the igniter and burner.

But you shouldn’t disassemble the boiler on schedule just because it’s time for cleaning.

In order not to take unnecessary actions, it is important to know the signs of clogging of internal parts and systems:

slow heating;
loss of power;
increased gas consumption;
pops when igniting;
constantly working burner;
extraneous noise during water movement;

uncharacteristic odors from the boiler;
difficult ignition;
reduction of pressure in the water circuit;
incorrect sensor readings;
no reverse thrust.

The boiler should be inspected if at least one of these signs appears. But most often, several symptoms of contamination of parts are observed at once.

For which rooms is it best suited?

AOGV 23 boilers are optimal for use in private homes, public or commercial premises. They require a separate room with ventilation, so installing the units in apartments is not recommended.

Also, production workshops with a large number of openings and technological hatches that disrupt the air exchange regime and create drafts are not suitable for operation. They often cause flames, which stops the heating system from working and creates the risk of gas leaks.

The best option is a separate room in the basement (ground) floor, with a window opening and an area of at least 8 m2.

How often should you clean

The need for cleaning arises when the following negative aspects are identified in the operation of the AOGV boiler:

with stable operation of the gas boiler unit, the temperature in the room decreased significantly;
gas and electricity consumption increased;
The smell of carbon monoxide began to noticeably appear in the room.

As a rule, the causes of such failures are clogging of the boiler. In order to understand where pollution accumulates, you need to know the structure of a gas boiler.

Cleanable nodes

Gas boiler installation. (Click to enlarge)

This type of equipment contains the following components that need to be cleaned periodically:

igniter;
burner with nozzles;
gas filter;
heat exchanger;
firebox;
chimney.

It is worth noting that cleaning each component of a gas boiler has its own specifics, which we will dwell on in more detail.

Igniter

When the igniter is functioning normally, its flame should look like a cone with a blue tint. If the flame turns yellowish, this means that the burner is dirty.

The cleaning procedure occurs in the following sequence:

shut off the gas supply to the boiler;
unscrew the igniter;
Clean thoroughly using a wire brush;
perform purging;
Reinstall the cleaned igniter.

Burner with nozzles

This part is the main one in the design of wall-mounted and floor-standing gas boilers, since it is intended directly for supplying fuel.

The sequence for cleaning the burner with nozzles is as follows:

the gas supply valve closes; the burner is removed from its installation location; the location of the nozzle is noted, and then it is carefully unscrewed; You need to carefully clean the nozzle with a brush; the burner is cleaned with a brush, and its hole is purged using available pumping equipment; the nozzle is inserted into the burner according to the mark; the burner is installed in place.

Gas filter

This device is designed to purify incoming gas from various types of contaminants and impurities.

Therefore, it is very important to regularly clean the filter from accumulated clogging.

Heat exchanger

It is worth knowing that the main purpose of the heat exchanger of a double-circuit boiler is how much water will be heated and at what speed.

It is also necessary to understand that this element of the boiler unit can become clogged both inside and outside.

The outer part of the heat exchanger becomes contaminated with soot, which negatively affects its functioning. This boiler unit can be cleaned of soot mechanically, in other words, cleaning is done with your own hands.

To do this you will need the following set of tools:

scrapers;
metal brush;
various shapes of brushes;
power tool with cleaning attachments.

The cleaning procedure is as follows:

gas supply and power supply from the boiler is turned off;
the heat exchanger is carefully removed;
cleaning is carried out using convenient tools;
the device is installed again in its place.

As a result, the throughput of the heat exchanger decreases, which generally affects the functioning of the entire gas boiler. The most optimal way to clean the inside is to flush the gas boiler heat exchanger using chemicals.

Among the reagents that are used to clean the internal walls, the following products can be distinguished:

adipic acid;
sulfamic acid solution;
special gel.

The booster consists of the following elements:

circulation pump;
reagent container;
electric heater.

The principle of cleaning the heat exchanger using a flushing device such as a booster is as follows:

to improve cleaning properties, the reagent is heated in a container;
Using a pump, the solution is supplied under pressure directly to the heat exchanger.

As a result of the circulation of the chemical, the scale lags behind the internal walls and comes out along with the waste solution.

Firebox and chimney

Although gas is a clean fuel, over time soot still accumulates on the walls of the firebox and in the chimney. The accumulation of this combustion product interferes with the normal functioning of the boiler, as draft is lost.

Therefore, it is recommended to carefully monitor the formation of soot and regularly clean the chimney and firebox. We hope that the information presented in the article will be useful to you when cleaning your gas boiler.

Watch the video, which shows in detail how to properly clean a gas boiler at home:

Functions and principle of operation of security automation

In accordance with regulatory documents, automation equipment for boiler installations must stop their operation by cutting off the fuel supply in the following situations:

the draft in the chimney is insufficient and there is a danger of burning;
the gas pressure in the supply pipeline is too low or, conversely, too high;
The flame on the igniter went out.

The listed situations can lead to the main burner going out and the room becoming gassed, which is unacceptable. For this reason, safety automatics for gas boilers must be installed on all old-style boilers where it was not provided by the manufacturer. Although it is often cheaper to replace a heater than to purchase and install automation on an old one. In addition to preventing gas contamination of the room or fumes, its functions also include maintaining the temperature of the coolant at a certain level specified by the user.

To understand how the automation of a gas boiler works, let’s briefly analyze its structure. It should be noted that both foreign and Russian manufacturers use the same operating principle in their products, although the design of the devices may differ significantly. Automatic gas valves from Italian manufacturers are traditionally considered the simplest and most reliable, which is why they are most common.

A prominent representative of such gas appliances is the Italian automatic SIT, or rather, its most popular modification 630 EUROSIT, whose device is shown below.

All structural elements are placed in one housing, to which gas pipelines are connected. In addition, a capillary tube from draft and temperature sensors (thermocouples), a gas supply line for the igniter and a cable from the piezoelectric element are connected to the device. Inside there is a shut-off solenoid valve, whose normal state is “closed,” as well as a gas pressure regulator and a spring valve.

Any automatic gas boiler equipped with a combined gas valve EUROSIT or another is started manually. Initially, the fuel path is blocked by an electromagnetic valve, which opens by pressing the adjusting washer, after which the fuel fills the chambers of the device and goes through a small gas pipeline to the igniter. While holding the washer, press the button of the piezoelectric device and ignite the igniter, heating the temperature-sensitive element for 10-30 seconds. This, in turn, generates a voltage that keeps the solenoid valve open, after which the adjusting washer can be released.

Then everything is simple, we turn the washer to the required division and thereby open access of fuel to the burner, which is independently ignited by the igniter. Since the automation of gas boilers is designed to maintain the set temperature of the coolant, human intervention is no longer required. The principle here is this: when heated, the medium in the capillary system expands and acts on the spring valve, closing it when it reaches a high temperature. The burner goes out until the thermocouple cools down and the gas supply resumes. You can study the operation of Italian SIT automation in detail by watching the video.

When cleaning is necessary

A gas boiler is a complex device, and disassembling it without a good reason is too expensive. To avoid taking unnecessary actions that could cost you a pretty penny, check out a number of signs that indicate a clogged heating element:

The boiler does not produce the required amount of heat, while consuming a large amount of fuel.
During operation of the device, extraneous noise appears, the presence of which was not observed before.
The water pressure from the tap decreases significantly.
The heating process of the batteries is slower than usual.

Gas consumption has increased

One of the key reasons why gas consumption increases significantly compared to the norm is the clogging of the heat exchanger with scale. The boiler requires more fuel to heat the exchanger to the required level. After cleaning the part, the consumption returns to the basic values.

Burner always on

A clogged heat exchanger means that the water takes a long time to heat up, and the turbine constantly pumps in new liquid.

Because of this, the burner is constantly working, trying to bring the water temperature to the required value.

Descaling solves the problem, allowing the boiler to operate normally, without interruptions.

Rumble and interruptions in the operation of the circulation pump

A clogged system makes it difficult for fluid to circulate, causing the pump to overload during operation. Because of this, the following appear:

extraneous noise;
interruptions in the operation of the device;
engine overheating.

Reduced pressure in the DHW circuit

A decrease in pressure in the DHW circuit is possible due to:

incorrect operation of the heat exchanger;
leaks in the pipeline system;
The hot water supply circuit is depressurized.

SAFETY INSTRUCTIONS

Persons who have examined this passport are allowed to service the device.

Installation and operation of the devices must comply with the requirements of the “Rules for the design and safety of operation of hot water boilers, water heaters and steam boilers with excess pressure”, as well as the requirements of the “Safety Rules for Gas Distribution and Gas Consumption Systems. PB 12 - 529", approved by the State Mining and Technical Supervision of Russia.

The operation of the devices must be carried out in accordance with the “Fire Safety Rules for residential buildings, hotels, dormitories, administrative buildings and individual garages PPB - 01 - 03”.

Operation of the device is only permitted with properly functioning automatic safety and thermal control.

Why does a gas boiler become clogged with soot?

The reasons for the formation of soot in boilers when burning natural gas may be different, but all of them, one way or another, are related to the property of the burned fuel, under certain conditions, decomposing into carbon and hydrogen. Modern heating units require precise adjustment of the burner device, taking into account the intensity of air supply and exhaust of combustion products.

The catalysts for soot formation are:

Incorrect ratio of gas and air proportions during combustion.
Poor quality fuel.

To reduce the percentage of soot in the flue gases, you will need to tune the boiler, check and, if necessary, replace the jets, and clean the nozzles from carbon deposits.

The formation of soot due to incomplete combustion of gas can be easily prevented if a specialist is invited to install and adjust the boiler. Every year, during seasonal maintenance, the operating parameters of the burner and the composition of the CO emitted are checked.

How to clean a gas boiler from soot deposits

Clean a gas boiler from soot at home? much easier than removing scale from the internal cavity of the heat exchanger. Carbon deposits are removed using the abrasive method. As a chemical reagent? use regular soda. Cleaning is done with a hard kitchen sponge.

You can dissolve soot with regular boiling water. If the carbon deposit thickness is more than 2 mm, special cleaning agents are used. First, the surface is treated with a metal brush. Through the furrows, the chemical solvent better penetrates the surface and removes soot.

How to clean nozzles on a gas boiler

There are several ways to clean carbon deposits on gas injectors:

Mechanical method - this is how gas workers clean injectors during regular seasonal maintenance. The ash is removed with a special tool that resembles a curved hook.
Using chemicals – heavy stains are removed with reagents. For cleaning, the burner device will need to be removed.
The ultrasonic method is a relatively new cleaning method that allows you to get rid of carbon deposits with minimal consequences for the burner and the nozzles themselves. It is carried out on specialized equipment.

Which gas boiler heat exchanger is less susceptible to scale?

Scale appears on heat exchangers of any type. The rate and intensity of deposit formation depends on the material of the water circuit:

Cast iron heat exchangers have the best resistance to the appearance of salt and mineral deposits. The service life of boilers is about 35 years. The circuit is made of cast iron, resistant to any aggressive substances.
The heat exchanger is made of stainless steel and is resistant to corrosion, but after several years of operation, deposits of metal salts begin to appear on the walls of the circuit cavity.
For copper heat exchangers, the first place in terms of the intensity of deposits is prepared. The process of scale formation is accelerated if aluminum fittings, adapters or radiators are used in the heating or hot water system.

Cleaning methods

There are three ways to clean a solid fuel boiler from soot, tar and tar: mechanical, steam and chemical.

Each of the methods has its own distinctive features. Let's look at each of them.

Mechanical

The process of mechanical boiler cleaning is based on removing combustion products from the walls of the unit using special tools. For this purpose, the following are used: pokers, various-sized scrapers, spatulas, metal brushes, and brushes.

Do not forget that you need to start the process of cleaning the boiler from soot only after the device has completely cooled down.

It is important that during the process of cleaning the boiler from soot, the damper is not closed. Removal of resin and tar from the walls of the unit is carried out as follows:

Removal of resin and tar from the walls of the unit is carried out as follows:

Initially, the heater needs to be warmed up. Resin and tar are quite hard, and when the boilers heat up, they soften and become easier to get rid of.
Next, using shovels and scrapers, you need to get rid of these deposits.
After the cleaning process is completed, you need to increase the temperature of the boiler. This is done so that the remaining resin and tar burn out.

Chemical

This method of cleaning a solid fuel boiler is very popular. It is based on the use of different chemical compositions.

To clean the unit with a chemical, you need to heat the reagent and use a special pump to fill the boiler system with it.

The most commonly used acids are sulfamic, adipic, and helium.

Adipic acid is diluted with water and carefully poured into the boiler using a pump. Once in the device, the mixture reacts with deposits, transforms into acidic salts and dissolves. At the next stage, you need to release the pressure and wait until the salts precipitate, and then wash them off with water.

Sulfamic acid is also diluted with water, only in a separate container. Then it needs to be pumped into the cooled boiler under pressure. Next, you need to wait a while for the acid to react with the plaque and rinse the unit.

In order to clean soot from a chimney, rock salt is most often used. It is added to the firebox the moment the fuel burns. However, this method is used only for preventive purposes. It will not be possible to completely get rid of soot with its help.

Potato peeling is more effective in combating soot. The method is as follows: while the fuel is burning, they need to be poured into the combustion chamber. Starch will begin to release along with the steam. It is due to this that the soot will soften and be removed from the chimney. After completing this procedure, the boiler must be thoroughly cleaned.

When cleaning a solid fuel boiler with chemicals, strictly follow safety precautions.

Steam

This method involves treating the walls of a solid fuel boiler using a steam generator. This way you will not only get rid of dirt, but also fungus and mold in your heating device.

Thus, you can clean the boiler from tar, soot and tar using any of the proposed methods. Some will take longer and require a lot of effort from you. Others will allow you to quickly get rid of deposits, but will be more expensive. In any case, the choice of method is yours. The main thing is not to forget to regularly clean the solid fuel boiler, because the efficiency of its operation will depend on this.

How to clean the heat exchanger of a floor-standing gas boiler

To disassemble a heating unit at home, you do not need any special tools; a regular set with screwdrivers, keys and pliers is sufficient. Preventive cleaning of the heat exchanger from soot and scale is carried out in the off-season, when the heating of the house is turned off. Having previously shut off the gas supply, we begin disassembling the boiler by removing the burner device in the following sequence:

Disconnect all wires from the gas valve.
Remove the thermocouple connected to the gas valve by a capillary tube from the combustion chamber.
Disconnect the gas supply pipe.
Unscrew the 4 nuts (or bolts) holding the stove with the burner. Pull the assembly out as shown in the photo:

The burner is removed together with the safety valve and mounting plate

The gas boiler burner can be cleaned without further disassembly using an old toothbrush. The igniter, piezoelectric ignition device and flame control sensor (if equipped) should also be cleaned of soot. Now you need to get to the heat exchanger, for which you need to remove the top cover of the boiler, disconnect the draft sensor and the chimney pipe.

In the opened opening you will see insulation covering the chimney casing. Carefully remove the insulation, and then unscrew the screws securing the casing and remove it. Below it is a heat exchanger, from which you need to remove steel turbulators, as is done in the photo:

When removing the turbulators from the heat exchanger, the soot spills downwards, so the first thing to do is remove the burner

Cleaning the turbulators is easy; this can be done with a regular brush with metal bristles. But cleaning the heat exchanger of a floor-standing boiler is best done with the help of simple tools made by yourself according to the size of the smoke pipes. If they have a rectangular cross-section, then you need to bend a convenient flat spatula and a small scoop-shaped scraper from thin metal, then nail it to a wooden handle.

For round flame tubes, these same tools are made slightly curved. First, the walls of the pipes should be cleaned with a scoop, after which the soot remaining in the corners should be removed with a spatula.

At the end of the work, all surfaces of the heat exchanger can be cleaned with a brush screwed to a long handle. The last step is to remove soot from the bottom, where it was poured when cleaning the smoke pipes. This is what a clean heat exchanger of a heating unit looks like:

You can take a closer look at how to clean a gas boiler at home in the video:

Mechanical cleaning of plate heat exchangers

You can clean the boiler from soot without removing the heat exchanger. To do this, just remove the cover, arm yourself with a stiff nylon brush and close the gas injectors so that dirt does not get in there. The whole process is clearly shown in the video:

https://youtube.com/watch?v=ccEAX_yoExc

If soot has stuck to the surface and is not removed by mechanical treatment with a brush, then the heat exchanger is removed and soaked in special cleaning solutions for several hours. Such products are available for sale in a wide range, examples include Fauch and MAZBIT+ products. But you can also use household chemicals - gels for cleaning grills and ovens.

Before disassembling the boiler, you need to disconnect it from gas and the igniter from electricity. In addition, it is necessary to drain the water from both circuits and the expansion tank. The secondary heat exchanger is removed first; it is located immediately behind the boiler lid. The primary (main) one is more problematic to remove, since you will have to disassemble the combustion chamber.

How to reassemble the AOGV burner block

Carefully reassemble all components in reverse order. Slowly, without distortion, lift this entire block so that the burner goes inside the housing, and the igniter and thermocouple assembly does not cling to the casing flange. Standing on the side of the pipes, slightly push the entire assembly towards you with a slight downward tilt so that the opposite edge of the pan rises slightly.

As you feed the pallet forward, simultaneously put on the two farthest hooks so that they engage the casing flange. Direct the hook closest to you into the cut-out groove, and when it fits into it, turn the entire pallet counterclockwise. The gas pipe should be directly under its branch pipe of the automation unit.

Check the presence and correct fit of gaskets and reinstall all tubes. Tighten the nuts on the igniter pipe and on the gas supply pipe with a wrench

Before reinstalling the thermocouple tube, very carefully clean its contact pads. It is recommended to tighten this nut not with a wrench, but with your fingers. Check the tightness of the connections for possible gas leaks and start the boiler

Check the tightness of the connections for possible gas leaks and start the boiler.

Automation unit for AOGV Economy boilers. Part 1. Important information.

Automation units for gas boilers AOGV Economy. Particularly important information. Date of entry of information: 06/28/2015.

Old sample. Special signs.

2. Gas is supplied to this block as if “from behind the block”. Those. You don't have a gas hose that goes straight to the unit. And the fitting for the gas supply is located at the back of the boiler body. The gas hose is connected to this fitting, which is located at the rear.

We call this block the old block. Why was it replaced? Our opinion Most likely, this was the case. Imagine that the pipe through which gas flows through the boiler jacket, i.e. through water or through antifreeze suddenly could not ensure reliability? What will happen then? Therefore, replacing this old block with a new one is directly related to the deterioration of the quality of materials and a decrease in their durability. And it’s not the plant’s fault, but the global situation itself—the desire to reduce costs—has led to this replacement. Therefore, the very meaning of the ideal technology for supplying gas to the unit through a heated boiler (and it really is almost ideal) was changed and made as simple as it was abroad.

2. We can always iterate over any block, no matter how scary it may be. In fact, this is pri-mi-tiv. And, by the way, everything ingenious is simple.

How to remove and clean the AOGV burner block

To remove the burner block, you need to rotate the boiler pan and disconnect the igniter tube, gas pipe and thermocouple contact tube from the automation unit. Then carefully unscrew the nuts on the fittings of the automation unit.

Remove the paronite gasket on the main gas pipe and check its condition. Check the gasket on the flare tube for wear; most likely, it will remain on the tee fitting.

After disassembling this unit, the pan can be easily rotated and the holder can be removed from engagement with the casing through the groove closest to the tubes. Supporting the tray from below, push it slightly towards you and disengage the remaining two holders. Lower the entire assembly to the floor and carefully lift it out between the legs of the boiler.

Check the condition of the main burner and clean it if necessary. Then inspect the pilot nozzle.
Unscrew the two screws holding this assembly in the assembled position (wick and thermocouple). To make unscrewing easier, treat the screws with WD-40, the process will be much easier.
Remove the box housing from the pilot burner to gain access to the nozzle. If necessary, remove deposits from the brass nozzle without any effort using fine sandpaper.
Clean the nozzle itself with a thin copper wire and blow it under pressure with a pump from the side connecting the tube to the tee.
While there is free access, very carefully clean the bend of the thermocouple tube with fine sandpaper; there may be a small layer of oxide there.

Let's consider the method for finding the above fault.

When repairing a gas boiler, testing begins with the “weakest link” of the automation device - the draft sensor. The sensor is not protected by a casing, so after 6...12 months of operation it becomes “overgrown” with a thick layer of dust. The bimetallic plate (see Fig. 6) quickly oxidizes, which leads to deterioration of contact.

The dust coat is removed with a soft brush. Then the plate is pulled away from the contact and cleaned with fine sandpaper. We should not forget that it is necessary to clean the contact itself. Good results are obtained by cleaning these elements with a special “Contact” spray. It contains substances that actively destroy the oxide film. After cleaning, apply a thin layer of liquid lubricant to the plate and contact.

The next step is to check the serviceability of the thermocouple. It operates in severe thermal conditions, since it is constantly in the flame of the igniter; naturally, its service life is significantly shorter than other elements of the boiler.

The main defect of a thermocouple is burnout (destruction) of its body. In this case, the transition resistance at the welding site (junction) increases sharply. As a result, the current in the Thermocouple - Electromagnet circuit.

The bimetallic plate will be below the nominal value, which leads to the fact that the electromagnet will no longer be able to fix the rod (Fig. 5).

Working with AOGV

It begins when the gas supply is blocked - the corresponding valve closes. And this is a general principle for similar work with any boilers and columns.

How to clean the burner of an AOGV gas boiler? After shutting off the gas, this element is removed from its position. The burner has a nozzle

It is carefully unscrewed and carefully cleaned with a brush. The burner itself is cleaned by blowing using a special pump. Then the nozzle and burner are returned to their place

Then the nozzle and burner are returned to their place.

These are general criteria. And the details are presented on the next two models.

First. AOGV 11.6-3. This is a reliable and practical device.

But after a certain period of operation, it is thoroughly cleaned. The process goes like this:

The burner block is removed

To do this, the pan of the apparatus is rotated, and three tubes are disconnected from the automation unit: contact, gas and thermocouples

Carefully unscrew the nuts located on the fittings of the automation mechanism. The paronite gasket on the main gas pipe is removed and its conditions are studied

If it is damaged, it needs to be replaced. The marked pallet is taken out through the groove, which is as close as possible to the tubes

The casing is also pulled out along with it. When fixing the lower part of the tray, point it towards you and remove the remaining holders (two pieces) from the engagement. This entire assembly falls to the floor. The main burner is examined and cleaned. The igniter nozzle is inspected. The wick and thermocouple are unscrewed. The box-shaped casing is separated from the pilot burner. This clears the way to the nozzle. If it is brass and there is plaque on it, it can be removed with fine-grained sandpaper. Cleaning the nozzle. To do this, thin copper wire and a blowing method under high pressure are used. The second action is carried out by a special pump from the side where the tube is connected to the tee

The same sandpaper is used to very carefully clean the bend of the thermocouple tube.

After this work, all the parts are assembled using the reverse algorithm. Smoothly, avoiding distortions, lift the entire block. The burner should be inside the housing, and the igniter and thermocouple should not touch the casing flange.

From the side of the tubes, the entire assembly should be tilted towards itself with a slight downward slope. The opposite side of the tray should rise.

Then feed it forward and simultaneously put on a pair of distant holds. They should be on the casing flange. The nearest hook goes to a cut groove. After it enters there, the entire pallet rotates in the opposite direction to the clockwise direction. The gas pipe should be positioned only under its branch pipe of the automation unit.

Next, it is tested how correctly the gaskets fit, and all the tubes are returned to their places. The wrench tightens the nuts on two tubes: the igniter and the gas tube.

Before reassembling the thermocouple tube, its contact areas are carefully but carefully cleaned. The nut here is tightened with your fingers.

The final stage is to check the tightness of all connections for potential leaks. If they are absent, the boiler turns on. If available, these places are covered with sealant, the nuts are tightened.

The second model is AOGV-23.2-1 Zhukovsky.

It works like this:

The nut is unscrewed so that the gas pipe passes through.
The angle, igniter and thermocouple are unscrewed.
All burners in the set stretch outward and extend to the side towards the user. If there are difficulties with their movement, loosen and unscrew the studs with pliers. Clean all jets and other components.
Disassembly of burners. To do this, unscrew 4 pins on both sides.
The plates with slots are removed from the top of the burners, then the springs. All parts are thoroughly cleaned.
Reassemble all elements in reverse order.

After reassembly, a leak test is carried out to examine how tightly the burners adhere to the body.

Manufacturers

If you want to purchase a higher quality and more expensive AGV, you can pay attention to the products of foreign companies:

BAXI and FERROLI. These devices have a good design and an electronic control unit.
RINNAI. Devices of this brand are distinguished by quality, reliability and ease of use.
ANIERIA. Relatively inexpensive, but very reliable boilers made in Korea.

Imported devices outperform domestic ones in efficiency, but lose due to their dependence on electricity. Before you turn on a foreign-made AGV, you need to connect it to the power grid. Considering that there are often power outages in the domestic space, this factor cannot be ignored when choosing a suitable device.

The choice of AGV is often based on the cost of equipment and operation. Domestic-made boilers are cheaper on their own, and they are much more profitable to operate. The total savings are approximately a third, based on similar indicators of imported devices.

About old-style boilers

AOGV is a later modification of the AGV brand. They, like their predecessors, do not have particularly high efficiency and do not have thermostat control. When gas was cheap, no one paid attention to low performance; today efficiency is one of the most important characteristics when choosing heating equipment. AGV models were distinguished by low-quality automation, which broke after one or two seasons of operation.

AGV and AOGV can work without automation: if it breaks down or is turned off on purpose, it will not interfere. When buying a heating boiler, you need to take care of a sufficient number of pipes - their diameter should not be less than two inches. If you take a smaller diameter, the circulation of the coolant may deteriorate - there will be additional costs for heating it.

What is the improvement?

The developers have made a number of improvements to the design:

Glass thermometers were replaced with Italian, more modernized ones.
German automation from Honeywell was installed.
Piezo ignition.
The appearance has improved thanks to the high-quality coating. The design has changed: the body can be round or rectangular. White color. Painting: powder.

Question about Danko

This brand has models with different automatic systems “Eurosit” and “Kare”. Below is an example of working with the second option on the Danko 24 model.

Removing the cover. The screws on the back and front are unscrewed, two at a time.
The American unscrews.
The two nuts that secure the burner are unscrewed.
The contact terminals are removed.
The clamp is removed. The thermocouple is pulled out.
The burner block is removed.
Cleaning burners. Surfaces are cleaned with a brush or toothbrush. Holes - with a vacuum cleaner.
Reassembly.
Leak test.

The mechanisms of Ross boilers from the “Lux” series, where tubular burners are arranged, are disassembled using a similar principle.

Start-up and operating instructions

The boiler is started after installation on a flat horizontal surface and connection of all communications:

Gas supply.
Forward and return lines of the heating system.

After installation, the system should be filled with coolant. The filling level is monitored using a signal pipe. The boiler is ignited using a piezo ignition unit or a lit match (Economy series).

IMPORTANT!

To start the boiler, you must first ventilate the room for 15 minutes. After this, open the gas tap, turn the knob to the “igniter on” position and push it in all the way. Wait in this position for 10-15 seconds, then press the piezo ignition button.

When a flame appears on the igniter, wait another 20-30 seconds, then release the handle. The pilot light should continue to burn. After this, you can set the required coolant temperature.

During operation, the user is not required to take any specific actions other than periodic cleaning of dust and soot.

Once a year you should invite a specialist to perform maintenance. For any problems, please contact the warranty or service center.
